IPC: B60K17/08
Filed: 1949-02-22
Abstract: 657,228. Variable-speed gearing. MORRIS MOTORS, Ltd. Feb. 22, 1949, No. 4771. [Class 80(ii) ] In a motor vehicle, the main drive from the engine shaft 1 to the input shaft 10 of the gear box is controlled by an electromagnetic friction clutch 4, and an underdrive from the shaft 1 to the layshaft 17, via shaft 11 and gears 12, 13 incorporating a one-way clutch 21, is controlled by a separate electromagnetic friction clutch 5. Both clutches 4, 5 are normally engaged, the clutch 21 over-running, but the clutch 4 is disengaged by a kick-down of the accelerator so as to bring in the underdrive. Clutch 5 is energized from the dynamo 22 while clutch 4 is energized from the battery 39 under the control of a switch 38 operated by a relay 35 energized from the dynamo. Both clutches 4, 5 are controlled by switches 25, 26 in series in the dynamo circuit, the solenoid switch 25 closing only .above engine idling speed, say at 500 r.p.m., while the switch 26, which is spring- closed and which incorporates a variable resistance 27, can be opened by a foot pedal and thereafter allowed to close gradually for starting. The relay 35 is ,in series with a toggle switch 33, normally closed but opened by a kick-down of the accelerator and reclosed as the accelerator approaches idling position, a delay unit 36, a switch 31 controlled by vehicle speed so as to close above say 20 m.p.h. and reopen at a slightly smaller speed, and normally-closed switches 29, 30 which are opened when the gear is manually changed to bottom or reverse. The delay unit 36 is shorted by a switch 32 which closes above say 40 m.p.h. The switches 31, 32, 33 are shorted by a switch 34 which closes when the shaft 10 rotates at above a predetermined speed, equivalent to say 40 m.p.h. in top gear, so as to cut out the underdrive above that speed. An emergency switch 40, shorting the switch 38, may be closed for touring purposes.

Title: Improvements in or relating to moulds for use in building walls
IPC: E04G11/34
Filed: 1948-02-18
Abstract: 642,195. Moulding concrete walls in situ. O'SULLIVAN, E. Feb. 18, 1948, No. 4806. [Class 20(ii)] A mould for casting a concrete wall in successive sections comprises two relatively movable units, one of which consists of a pair of spaced side plates and connecting means therefor, the other unit consisting of an end plate positioned by the previously cast course of the wall and which is movable between the sideplates, so that after a section of the wall has been cast, the end plate provides local support therefor while the side plate unit is moved relatively thereto to its new casting position. For a cavity wall end frames 1, 2, Fig. 1, which may be rigid or adjustable, carry side plates 13, 14 and position a core 19 which is supported on a metal &c. strip 22 carried by wall ties 65. The strip 22 may be formed as a bar of lengths of U-section sheet metal interengaging end to end. The strip 22 has a series of abutment stops 55 for pins 46 on a triangular shaped frame 40 which carries the mould end-plate 35, this plate, when in moulding position, bearing on strips 37 the side plates 13, 14. After a section of the wall has been moulded against a previous section 66, the unit comprising the side plates, end frames and core is slid past the fixed end plate 35 to a new casting position, the end plate and its carrying frame then being removed and advanced to a position in which the pins 46 abut against the next stop 55, this position corresponding to correct location of the end plate 35 relatively to the side plates. Draft is provided on the various surfaces of the side plates and core to facilitate movement relatively to the cast concrete. The mould may be closed at the end opposite to the plate 35, for casting an end section, by a plate 25 Fig. 3 having lugs 32 to hook over the top of the frame 2 and a bar 30 to engage behind lips 33 on the frame 2. For a solid wall, supporting strips 170, Fig. 6 are fixed to the sides 113, 114, to bear on the previous course of the wall, and a guided core member 173 is provided on the frame 102 to form slots such as 172, to receive a positioning lug 146 on the frame 140 supporting the end plate 135 when the next course of the wall is cast. In a modification, to avoid the formation of grooves in the wall by the supporting strips 170 on the mould sides, these strips are dispensed with and the mould is supported by a bar 280, Fig. 7 guided in the plate 235, the frame 240, which carries the plate 235, being counterweighted to compensate for the weight of the mould.

Title: Improvements in processes for removing catalysts from hydrogenated oils
IPC: B01J23/94
Filed: 1952-02-27
Abstract: A process for the removal of nickel catalyst from hydrogenated oil comprises incorporating phosphoric acid or sulphuric acid and a clay with the oil and filtering the mixture.  A few hundredths (for example one to four) of 85 per cent syrupy phosphoric acid may be added directly to a mixture consisting of the hydrogenated oil (containing the catalyst) and the desired amount of clay prior to filtration.  The clay may be merely leached out with, for example, a solution of sulphuric acid and then pulverized before use; and it may be incorporated, in the proportion of from one half to one per cent, in the oil prior to its being pumped to the hydrogenation tank. Acidified clay slurry may be mixed with the oil at, or just prior to, the filtering operation.  Prior to treatment with acid and clay the oil may be filtered to remove substantially all the catalyst therefrom except that subsisting as a colloidal suspension.

IPC: H01L29/86
Filed: 1968-02-02
Abstract: 1,185,971. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 29 Jan., 1969 [2 Feb., 1968], No. 5358/68. Heading H1K. In a method of manufacturing semi-conductor elements from a slice of semi-conductor material, grooves 6 are formed in one face 2 of the slice to define the individual elements, which are later severed, and a P-type region is formed in the N-type slice such that the resultant PN junction extends beneath the grooves to a depth 8 such that after the elements are separated the PN junction in each element is located such that when avalanche voltage is applied across the junction the depletion layer thus formed extends over the surface of the element a greater distance than its thickness in the bulk of the element. The PN junction may be formed in two stages. Initially on an N-type slice a thin P-type layer is formed, as by epitaxy or vapour deposition, and the grooves are etched inwards through this P-type layer into the N- type material, and the P-type layer 5 is later driven in to the required depth. A further P- type layer of depth 8 is then diffused into the grooved surface of the slice and forms with the first P-type layer a region having a PN junction of the required configuration. The slice is cut, or scribed and broken, along the centres of the grooves to produce the separate elements. These elements have one or more PN junctions and preferably have inclined peripheral surfaces between the major surfaces.
